Miggo AIRoot Cause Analysis

The vulnerability stemmed from StreamMessage deserialization using ObjectInputStream without proper validation. The commit f647e5d introduced WhiteListObjectInputStream and modified RMQStreamMessage's constructor to enforce trusted packages. The original readBody method (using raw ObjectInputStream) and constructor (lacking trusted package handling) were the vulnerable points, as they allowed deserialization of untrusted payloads.
